Abstract:
A method for continuous High Internal Phase Emulsion (HIPE) foam production. A HIPE is produced then extruded onto a belt. After polymerization, a portion of the saturated aqueous phase is removed using a vacuum box. A nip insert is inserted under the vacuum box to raise the vacuum box leading to improved uniformity of the HIPE in the cross direction along the belt.
